Marcelo,
You've posted in the wrong forum. You might get a response in the Roland 'general' forum, as this forum is is for JV/XP/XV series of Roland synths, only (pro keyboards, not home units).
Generic advice: listen to both units in the store and decide which makes you grin more: after all, it's you (not us) who has to be happy with the choice.
Regards,
Chris
